debugWordWrap does not account for \n properly

This is not very useful for panicking and can produce very odd and erroneous panic messages that are not consistent with the toString() of that object.

Currently observed with Scene2D's printing of its adjacency list, where the debugWordWrap treats spaces as places to break and does not realize that the string provided already has wraps.

Instead of treating \n as real new spaces, it instead treats it as a normal character.

Maybe forward this to Flutter's issues board?

Oh im dum, in the debugWordWrap documentations they state:

The message should not contain newlines (\n, U+000A). Strings that may contain newlines should be String.split before being wrapped.

LOL. Yea it's just an implementation error due to my ignorance
